Description

Compound plant extract with oil control and acne removal effects and application thereof

Technical Field

The invention relates to a compound plant extract with oil control and acne removal effects, which is mainly used for preparing functional skin care products and belongs to the field of daily skin care products.

Background

With the aggravation of the reasons of living pressure, irregular life, food safety, environmental influence and the like, pox is one of the skin problems which afflict many young people. Pockmark is a chronic inflammation of hair follicle sebaceous glands, is common in young men and women in the development period of youth, mainly occurs at shoulder blades of facial muscles and breast muscles to form papules, is called as acne in traditional Chinese medicine, and is called as acne in western medicine. It is often manifested as acne, papules, pustules, nodules, cysts and scars.

Mechanism of pox formation: the increase of androgen can increase the secretion of sebaceous gland, and make the hair follicle and sebaceous gland hyperkeratotic, and the flat dead cells fallen from cuticle can be combined with sebum to produce mixture. If these mixtures are not free to drain out of the skin surface and pool in the hair follicle, a lipid plug is formed. Mature comedones are formed when these abnormal keratinocytes aggregate and the lower funnel swells. Sebum is broken down by bacteria present in the hair follicle to produce fatty acids which stimulate the follicle to cause inflammation, causing the follicle wall to rupture and the follicle contents to enter the dermis, causing an inflammatory response of varying degrees around the follicle.

At present, antibiotics such as metronidazole and the like are used for carrying out antibiosis and antiphlogosis on a plurality of acne-removing products on the market, and the products have certain effects on removing acnes, acnes and the like, but after long-term use, the products can stimulate the skin to cause contact dermatitis which is manifested as erythema, edema, erosion, pruritus and the like, and more serious, the drug resistance to the antibiotics is caused, and health hidden troubles are caused. Therefore, the development of a safe and effective oil-controlling and acne-removing product has very high practical application value and market value.
